tube solar collectors. Heat pipe type has advantages in certain aspects, such as anti-freezing, rapid start-up, resistance to high pressure, but the accumulated incondensable gas in heat pipe can restrict the normal operation and shorten collector service life (He ZN. et al 1997). Compared with heat pipe evacuated tube collector, using U-pipe to extract heating energy can maintain …
